IMPROVEMENT IN GAS-HEATING APPARATUS.

Specification forming part of Letters Patent No. 40,591, dated November10, 1863; antedated November 2, 1863.

To all whom it may concern.-

Be it known that I, S. LLOYD WIEGAND, of

the city of Philadelphia, in the State of Pennsylvania, have invented anew and improved apparatus for burning gases and vapors, and utilizingthe heat generatld thereby anl 1 do hereby declare that the following isa full and exact description thereof, reference being had to theaccompanying drawings, and to the letters of reference marked thereon.Figure l is an elevation of this apparatus. Fig. 2 is a sectionalelevation exhibiting the internal arrangements. Fig. 3 is a horizontalplan.

The same letters of reference refer to the same parts in severalfigures.

A represents a boiler secured to the base E by means of the bolts G andring G bearing upon the three projections marked T, cast upon the sidesof the boiler. To the side of the boiler A is attached a feedingapparatus, 13, provided with a valve, for receiving water, and a valve,U, for discharging water into the boiler A, and a valve, V, foradmitting steam from the boiler. The operation of this feeder isidentical with the operation of the oil-globes in general use forlubricating steamcylinders and steam-valves. A neck, is screwed into thetop of the boiler, and contains the screw-valve S for opening andclosing the connection, and regulating the flow of steam through thepipe P, from which the steam is conducted to be used. Upon the side ofthe neck 0 opposite to the pipe P is another pipe,Q, having at itsextremity a safetyvalve,R. Inside of the boiler A is a cylindric tube,N, made of wire-gauze, attached to the neck 0, for the purpose ofpreventing-the water from foaming up into and passing out of the pipes Pand Q.

Y is a small screw, made slightly conical, screwed into the boiler A,byloosening which a deficiency of water in the boiler A can beascertained,

I is a tube for receiving gas or vapor, and conducting it to thejet-pipe H, from which the gas issues and induces a current of airthrough the inverted funnel J.

L is a tube making in effect a continuation of the funnel J, andaffording points of support to the boiler A, which rests upon-theprojections Z Z, which may be formed on the boiler A or on the tube L,or may be made a separate piece or pieces, as may be most convenient inconstructing them.

X is a funnel made of wire-gauze or other perforated material of suchform as to correspond with the shape of the boiler, and is an extensionof the tube L.

O is a fender or chimney, of wire-gauze or plate metal, for the purposeof protecting the flame from cold drafts of air and confining it to theboiler. c

M M are arms for supporting the tube L within the base-ring E, and F F Fare feet for supporting the base E. KK K are handles projecting from thefunnel J for the purpese of rotating it, and thus screwing it up or downin the tube L, in the manner which will be understood by reference to.the parts in Fig. 2, the space or annular opening between the funnel Jand jettube 11 being thus regulated at the pleasure of the operator.

The operation of this apparatus is as follows The flame of a lightedtaper or match being introduced between H and J, a small amount of gasor combustible vaporintroduced through the tube I is thus ignited at theaperture of the jet-pipe H. Upon increasing the flow of gas in I, theflame is driven up through the funnel J and tube L, and induces anupward current of air in the direction of the arrows in J and L, which,mingling with the gas, burns in the funnel X,and if more gas passes intothe funnel X than can burn there, it escapes through the apertures inthe guaze, and mingling with the air passes up inside of the fender orchimney O, and is there consumed, an upward current of air being inducedand maintained by the heat through the spaces between the arms M andtube I and base-rin g E, which current, passing between the funnel X andfender or chimney O in the direction of the arrows in Fig. 2, suppliesany deficiency of air for the complete combustion of the gas. The supplyof air through J is regulated by screwing it up or down.

I do not claim, broadly, the use of a jetburner, H, and an invertedfunnel and chimney for introducing a supply of air to the jet, the samebeing old and well known as the Bunsen burner, audI also disclaim theburning ofmixtures of gas and air by admitting additional supplies ofair through apertures of wire-gauze overhanging the burner, or anyapparatus for so doing, the same having been done by Thomas Shaw, ofPhiladelphia, and patented by him but WhatI do claim as my invention,and desire to secure as such by Letters Patent, is-

1. The combination of the burner H and adjustable cap J with the funnelX, when used in the manner and for the purpose set forth;

2. Combining the external fender or chim- S. LLOYD WIEGAND.
